Good Morning.
I tested my Navi now, but the problem is still present.

If I unlock the vehicle and make the ignition key on position, I cannot see times the BMW boot LOGO. The Navi is not booting?!?
The LOGO comes then approximately after 2 minutes. After some minutes, if I drove loosely, I switch the radio on and I know on the right of the data, where I am and as high I am to the sea mirror-image gene and so on, not to see. Navigation does not go at all.
I will make the Navi now again on V26. I do not continue to know.
Have you still ideas?
